Optimization of Processing Parameters of Batch Annealing in Cold-rolled IF Steel

By the method of orthogonal design, the experimental work was carried out to simulate the industrial batch annealing. Using stepwise regression method to analyze the data gained in the experiment, the equations of relationship between processing parameters of batch annealing and mechanical properties of products have been established. And the effect of processing parameters of batch annealing on mechanical properties of IF steel sheet was investigated systematcally from mono-factor and poly-factor.
